ATTORNEY United States Patent 3,006,383 PILE CARPET Levon Mahmarian, 30424th St., Union City, NJ. Filed Sept. 11, 1959, Ser. No. 839,508 7Claims. (Cl. 139406) This invention relates to loop pile floor coveringand has for an object to provide a pile fabric of the above type havingnovel and improved characteristics.

Another object is to provide a loop pile fabric in which the loops haveadded resilience and resistance to crushing.

Another object is to provide a fabric of the above type in which thepile coverage is increased over that usually obtained by the same pileweight and density.

Another object is to provide a loop pile fabric of the above type inwhich the loops are highly resistant to permanent deformation.

Other objects and advantages will be apparent as the nature of theinvention is more fully disclosed.

The nature of the invention will be better understood from the followingdescription, taken in connection with the accompanying drawing in whicha specific embodiment has been shown for purposes of illustration.

In the drawing:

FIG. 1 is a warpwise section through a loop pile fabric embodying theinvention;

FIG. 2 is a fillerwise section taken on the line 22 of FIG. 1;

FIG. 3 is a partial warpwise section similar to FIG. 1 illustrating afurther embodiment of the invention; and

FIG. 4 is a broken elevation illustrating a wrapped filler yarn.

Referring to the drawing more in detail the invention is shown asapplied to a loop pile fabric of the usual type woven over transversepile wires. The fabric comprises a plurality of filler shots 10, boundby chain warps 11 to form a backing. Pile yarns 12 are bound underselected filler yarns and form upstanding loops 14 therebetween, suchloops 14 forming the pile surface of the fabric. A fabric of the aboveconstruction may be 'WOVBH on a standard velvet carpet loom. Theinvention is equally applicable however to loop pile fabrics woven on alacquard loom or on a leno-type stationary wire loom or to tufted orknitted fabrics having similar pile loops. A specific embodiment hasbeen shown for purposes of illustration only.

In accordance with this invention a fillerwise yarn 15 is laid througheach fillerwise row of pile loops 14. This yarn 15 is composed of a softresilient and flexible material such as natural or synthetic rubber or arubber-like material such as synthetic foam rubber or sponge rubber,

for example polyurethane or Curon, a product of (hirtiss- WrightCorporation.

In the form shown in FIGS. 1 and 2 yarn 15 is elongated in cross sectionin the vertical direction so as to conform in general to the shape ofthe loops. The yarn 15, however, may be round in section or of any otherconvenient shape.

FIG. 4 illustrates a yarn 15a of this character which is round insection and is provided with a core yarn 16 of cotton or the like andwith a wrapping 17 which may also be of cotton or the like. Either thecore 16 or the wrapping 17 may of course be used independently in orderto control the fillerwise yarn 15 and limit the stretch.

As shown in FIG. 3 the fillerwise yarn 18 is round in section and iscomposed of a spun yarn such as wool or Dacron. The weave in FIG. 3 isotherwise similar to that of FIG. 1 and the various elements have beengiven the same reference characters.

The filler yarn 15 or 18 may be of a size to nearly fi=ll the interiorof the pile loops 14 while leaving a substan- 3,006,383 Patented Oct.31., 1961 tial clearance between the filler yarn and the upper part ofthe loops 14.

When a fabric of the above type is used as a floor covering theresilience of the yarn 15 or 18 gives the pile surface a soft springyfeel and any deformation of the pile loops caused by Walking orfurniture is immediately restored when the compressing force is removed.Each loop is thus supported by the filler yarn and by the adjacentloops. Hence the loop has an increased covering power and othercharacteristics of a carpet having a greater pile density.

Due to this added support the pile yarns 12 may be made of a soft yarnsuch as Wool or a synthetic material in continuous filament or spunstaple form of a character which would normally possess insufli'cientstiffness for loop pile purposes. The entire fabric including the pileyarns and the filler yarns 18 may be made of a material such as sisal,jute or hemp, the filler yarns providing the resilience which isrequired for loop pile fabric.

Although a specific example has been shown and described it is to beunderstood that various changes and modifications may be made thereinand the invention may be applied to various uses as will be apparent toa person skilled in the What is claimed is:

l. A loop pile floor covering comprising a backing and pile loops boundtherein and extending upwardly above the surface thereof, said loopsbeing disposed in aligned rows, and a fillerwise yarn of a softresilient material extending through the loops of a row, said fillerwiseyarns being disposed above said backing and being of a size to fill aportion only of the area of said loops and being adapted to hold saidloops at least partially distended above the surface of said backing,the upper part of said loops normally extending above and being spacedfrom said fillerwise yarns to permit said loops to be at least partiallycompressed before being brought into engagement with said fillerwiseyarns, said loops normally when in extended position enclosing andshielding said fillerwise yarns from view and forming substantially theentire exposed surface of said floor covering.

2. A loop pile floor covering comprising a woven backing composed offiller yarns and warp yarns, pile loops bound under said filler yarns,said loops extending above said backing and being disposed in alignedfillerwise rows, and additional fillerwise yarns of soft resilientmaterial extending through the aligned loops of said rows, saidfillerwise yarns being disposed above said backing and being of a sizeto fill a portion only of the area of said loops and being adapted tohold said loops at least partially distended above the surface of saidbacking, the upper part of said loops normally extending above and beingspaced from said fillerwise yarns to permit said loops to be at leastpartially compressed before being brought into engagement with saidfillerwise yarns, said loops normally when in extended positionenclosing and shielding said fillerwise yarns from view and formingsubstantially the entire exposed surface of said floor covering.

3. A loop pile floor covering as set forth in claim 2 in which saidfillerwise yarns are composed of a material selected from the groupconsisting of natural or synthetic rubber, synthetic sponge andsynthetic foam rubber.

4. A loop pile floor covering as set forth in claim 2 in which saidfillerwise yarns are composed of a synthetic foam rubber and include anon-stretchable yarn to limit the stretch thereof.

5. A loop pile floor covering as set forth in claim 2 in which saidfillerwise yarns are composed of a synthetic foam rubber and include -awrapping of a non-stretchable yarn to limit the stretch thereof.

6. A loop pile floor covering as set forth in claim 2 in which saidfillerwise yarns are composed of a synthetic foam rubber and include acore of a non-stretchable yarn to limit the siretch thereof.

7. A loop pile floor covering as set forth in claim 2 in which saidfillerwise yarn comprises a soft spun yarn. 5
